House 229, former workers' residence Jenny, Spoerry & Cie., former gypsum mill

The gypsum mill was built by Johann Rheinberger in 1800. It was run profitably as such until the middle of the 19th century. The mill was then acquired by Johann Jakob Spoerry in 1881 and converted into two residential units in 1900. The two-storey building opened up new room layouts and an external staircase had to be built to access the upper apartment.
